DYEING APPARATUS Oriizinal application filed March 11, 1926, Serial No. 93,821. Divided and this application filed October 37, 1926. Serial No. 144,412.

This invention relates to dyeing'apparatus and more particularly to apparatus for carrying out the method of dyeing one or more predetermined parts of an absorbent mass, which is described and claimed in Patem No. 1,724,015, issued to Eclipse Textile Devices, Inc., on August 13, 1929. The present application is a division of my co-pending application filed Marchll, 1926, Serial No.93,8-21.

The object of the apparatus with which the present application is concerned is to facilitate carrying out the method of dyeing in which the dyeing liquid is passed rapidly through a predetermined limited part of a wound mass of yarn, coloring this part of the yarn only; and more particularly to aid in carrying out a specific method of spot-dyeing yarn wound in the form customarily known as a cross-wound cone of yarn, This specific method, which is described'and claimed in m aforesaid co-pending application, is as folows: ,7

A cone of yarn is positioned with the axisv of its core vertical and with the larger open end of its core pointing upward. The cone is rotated ra idly, for example, at a speed of 2000 R. P. M ab0ut' the axis of its cone. During the rotation, liquid is supplied to limited zones of the inner surface of the mass of yarn,

that is, the surface adjacent to the core.

The liquid used is a dyeing solution in which the coloring matter is suspended, or,

'more desirably dissolved, in water or other relatively non-volatile liquid (as distinguished from a volatile liquid, uch as alcohol, which evaporates quickly) The dyeing solution is preferably hot and may include about 20% of an assistant, such as Turkey, red oil, or other chemical to assist the coloring matter in penetrating the pores of the yarn.

The solutionis poured into the upper, open end of the corebefore or during the rotation, reaches parts of the inner surface of the mass through perforations previously provided in two spaced zones of the core, is forced by centrifugal force into and through the zones of the mass of yarn which lie radiall outward from the two. perforated zones 0 the core, and is then thrown oif from the outer surfaces of these zones before it can soak into or color the portions of the mass between and outside zones has colored them to the desired-tint.

The supply of liquid to the inner surfaces of the zones is then stopped, and the rotation is continued until no further liquid or mist is thrown off from the outer surfaces of the zones. This results in leaving the two zones which have been 'dy'ed, substantially dry, an thus eliminatesall danger of subsequent col oring of other. parts of the mass by liquid soaking into them from the dyed zones.

The method described may be modified to produce a single colored zone, or any desired number of separated colored zones, by perforating a single zone, or the desired number of separate zones, of the core of the mass.

A convenient form of apparatus, embodying the present invention, and adapted to aid in carryin out the method described is illustrated in t e accompanying drawings in which Fig. 1 is an elevation in axial section; and

the apparatus shown in Fig. 1.

The apparatus illustrated includes a verti- .cal shaft 10 supported on spaced bearings 11. The shaft may be rapidly rotated by means of a power-driven belt 12 passin over a pulley 13 fixed on the shaft, or by other convenient means. A foraminous frusto-conical holder 15 is secured to the upper end of the shaft 10. The holder 15 is enclosed by a fixed casing 16 having at its lower end an opening 17 for the passage of the shaft and at its upper end a large opening 18 registering with the large open end of the holder 15 to permit placing of a cone of yarn C in the holder. The casing is provided with a valve-controlled drain pipe 19 and with a flange 20 surrounding its lower opening 17 to prevent liquid from reaching the bearings of the shaft 10.

The core C of thecone C is provided at two spaced zones with closely spaced perforations C, C. Liquid may be introduced into the core C from pipe 25, extended through the opening 18 in the casin 16 into the large open end of the core C This pipe ismounted so that'itmay be moved to permit the removal of the cone U and the insertion of a new cone.

Adeflector 26 is provided to prevent the liquid in the hollow core C from splashing over the upper end surface of the cone C. The deflector has a conical portion 27 fitting into the large end of the core and an upstanding lip 28. y

be carrying out of the method already described by means of this apparatus will result in dyeing two spaced zones C, C of the mass which lie radially outward from the sets of perforations C C leaving'the remainder of the mass uncolored.

The modified deflector 26, shown in Fig. 2, may be substituted for the deflector 26.

The lower portion 27 of this deflector forms a conical cup fitting against the entire inner surface of the core of the mass, so that the deflector is held very firmly within the core.

The cup 27 of the deflector is provided with two series of openings 30, 31, which register with the perforations C C of the core C when the deflector 26 is inserted in this core. The deflector 26 may, however, be used with a core 0* which is perforated throughout, since the two sets of openings 30, 31 of the deflector limit the supply of the liquid to the inner surface of the mass to two spaced zones.

What I claim is 1. Apparatus for dyeing a cone of yarn, comprising a hollow conical perforated core on which the yarn. is wound, means for rotating the yarn and core with the open end of the core upward, means for supplying liquid to-the interior of the core through its open end, and means for preventing said liquid from splashing out of the open end of the core during the rotation.

2. Dyeing apparatus, comprising the combination with means for rotating a cone of yarn wound on a perforated core and means for supplying liquid to the interior of said core, of a conical cup fitting into the core, containing lateral perforations, and having a lip extending outward from the open end of the core. 1

3. Apparatus for spot-coloring yarn on the cone by means of cehtrifugal force, comprising a conical cagerotatably mounted with its larger end uppermost and open to receive a cone ofyarn and to confine the outer surface thereof, means for applying a coloring liquid to a limited portion of the interior sur- 'face of the cone of yarn in the cage, and

means for rotating the cage with the cone therein at a rate of speed sufficient to cause the coloring matter to pass radially through the cone from its point of application, leaving the remainder of the cone uncolored.

4. In an apparatus for spot-coloring yarn wound in cone formation, a conical cage for frictionally engaging the periphery of the yarn cone, means for rotating the cage with the cone therein, a hollow conical mandrel frictionally engaged with the interior surface of the yarn cone for receiving rotary motion therefrom, and means for introducing a coloring fluid into the mandrel, said mandrel having restricted passages communicating with the interior of the yarn cone for permitting the flow of the coloring fluid to and through the yarn by centrifugal force as the yarn cone is rotated.

5. In an apparatus for spot-coloring yarn wound in hollow mass formation, a cage rotatable about a vertical axis and open at the top and provided with perforated peripheral walls for frictional engagement with the outer peripheryof the yarn mass, a rotary mandrel coaxial with and projecting into the upper end of the cage for frictionally engaging the interior of the yarn mass, said mandrel being provided with means for applying coloring liquid to limited portions of the interior area of said mass, and means for retating the cage and mass therein together with the mandrel at a rate of speed suflicient to cause the coloring liquid to pass from the interior to the peri hery of the mass of yarn. 6. Apparatus or spot-coloring yarn wound in hollow mass formation, comprising means for introducing a coloring liquid into the interior of the mass into contact with a limited zone of the inner surface thereof, means for rotating the mass at a rate of speed sufiicient to cause the coloring liquid to pass from the interior through and to the exterior of the portion of the mass lying radially outward from the zone to which the coloring matter is applied, and foraminous means confining the outer surface of the mass during such rotation to prevent disruption of the mass.

In testimony whereof I have hereunto set my hand.
